differential equation problem :( 1. The problem statement, all variables and given/known data I'm given a function acceleration a=-1.5*s, where s is a position. I need to find a in terms of t. 2. Relevant equations 3. The attempt at a solution I know that a is also equal to d^2*s/dt^2. Therefore d^2*s/dt^2 is equal to -1.5*s. By dividing by s and multiplying by dt^2 I get d^2*s/s=-1.5*dt^2. At this point I'm not sure what to do. If I can figure out how to get rid of the dt^2 and the d^2*s, then I can probably solve the rest of the problem. I imagine I need to integrate but am not sure how that would work out.
